From Under the Water -- Part One

Segment 14 - Air Date: May 6
((Anchor Intro))
Researchers at Lake Tahoe are studying everything from what goes into the lake to what
is already there. One such researcher from the Desert Research Institute is out on the lake
regularly measuring the turbidity of the water. In tonight's Lake Tahoe Report, Shelly
Purdy explains what turbidity is all about.

((Track 1))
Researcher Ken Taylor takes his boat out on Lake Tahoe throughout the year. He drives it
right next to the shoreline - circling the entire lake. As he drives, the boat pumps water
from the front to an instrument inside that measures the turbidity of the water.

"The water is pumped up through this glass cell and light shines through it and scatters
the light and that gives us an indication of how clear the water is."
((Track 2))
If there are a lot of particles like dirt and sediment in the sample?then the water is
considered very turbid. In other words - it's difficult to see through the muck that's
clouding the water. As Ken Taylor trolls the shoreline of Lake Tahoe, sophisticated
computers inside his research boat plot the dirtier areas, shown in red, and the cleaner
areas, shown in blue.
((SOT tape 2 @ 35:29))
"It allows us to find out what neighborhoods are causing problems and what
neighborhoods aren't causing problems and also allows us by doing surveys at different
times of the year, what types of storms are creating problems."
((Track 3))
The information he collects is then used to plan cleanup efforts and other remediation
projects in the areas that need it most. With the Lake Tahoe Environmental Education
Coalition, I'm Shelly Purdy for KOLO News Channel 8.

Lake Tahoe's shoreline have biggest problem with pollution, visit our website at

and personal with algae. It's that slimy green stuff becoming more and more common at
Lake Tahoe.
